Abstract A gas-mediated fabrication of centimeter-scale two-dimensional (2D) semiconductors and ultraviolet photodetector by a liquid metal-based printing was reported. Various large-scale 2D materials (Ga 2 O 3 , In SnO) were demonstrated to be directly printed at ambient air on different substrates. Such represents generic, fast, clean, scalable technique quickly manufacture semiconductors. The electrical properties explored quantify the films, which somewhat deficient in previous studies. particular, explore facilitate advantages this semiconductor functional electronic applications, strategies for realizing fully Ga /Si heterojunction via low-temperature low-cost processes developed. device exhibits excellent sensibility rapid photoresponse times. This work offers feasible way develop high-performance mass production. It also suggests promising direction making photoelectronic systems is expected extensively useful coming time.
